- When creating a match or tournament, the TD should have the option of insisting on a convention-card.
- To do this, the TD would simply specify a default card ("SAYC", "Simple Acol", "GIB 2/1" or whatever).
- BBO would automatically assign the default card to those who failed to post their own card.
- The icing on the cake would be if a card triggered an FD feature like StanMaz's BBOAlert.

"to my mind, though I am native here
And to the manner born, it is a custom
More honour'd in the breach than the observance."
Perhaps advanced players with complete knowledge of every nuance of every system will have no problem. I suspect that you are being a little optimistic.

The Laws of Bridge do not use the term convention card, it is system card, and there is no requirement to have them in the Laws itself. It is down to the Regulating Authority (RA) to decide how partnership agreements should be conveyed to the opposition. On BBO the RA is typically the ACBL, EBU, FFB, tournament organiser or table host.
I don't see the purpose of forcing partnerships to adopt a system that they do not know or play. Now there is little chance of the opponents alerting correcting or communicating partnership agreements when they don't know what they are. I guess at least half the pairs who believe they can play SAYC don't know that Jacoby 2NT is part of this system.
I am all for complete disclosure but this proposal will not help and will antagonise a large percentage of the BBO population for no good reason.

There's a fundamental problem with Convention Cards and BBO's inability to let me edit mine (they show up empty) or display opponent's CCs during play of the hand. I have a fairly complete set of CCs linked to my regular partners that should be available to my opponents during play.
My partial solution is to use BBOalert's shortcuts to display a URL to the appropriate CC at the beginning of each round.

- The subject was to the rules of Bridge, which include regulations as well as laws.
- Regulating authorities tend to insist on convention-cards (aka system-cards).
- Vampyr complains about the dearth of convention-cards in EBU on-line events.

As often happens, I think nige1 has a good point but perhaps made it too bluntly.
Yes it is up to the RA (another WBF concept that online play brings into question), but usually they do decide that a system card is obligatory.
In any case there are good arguments for obliging partnerships to follow some documented agreement, of their own design or not.
The real problem with all this on BBO is that the available "standard" systems are almost useless as standards: SAYC is obsolete, ineffective and complex,
GIB 2/1 (misleadingly named "2/1") is obsolete, effective but even more complex, Simple ACOL is comprehensible to about 10% of the BBO population.
Add in that it is not easy to create and use a custom card (only the obsolete flash client seems to really support it and the documentation is meagre)
and that BBO itself gave up prematurely on self-alerting systems and is doing nothing to support BBOAlert, and the situation is difficult as I see.

You can't make it drink
Or, in this case, post whatever convention cards you want
It doesn't mean that people's bids will be in any way consistent with them
In order to get anything like this to work, you need to focus on efforts to standardize people's bidding
In turn, this requires conscious long term efforts around teaching methods to beginners
Trying to layer on some technical fix ain't going to work

Why are your CCs not showing up?

But which card? BBO have 4or5 “default” cards available. Definitely these would be useful for pick-up partnerships. But it seems like a minor issue, since pick-up partnerships are rare.
Regular partners should have a card, even if it takes awhile to modify one of the stock cards. By the way, the format is truly awful, and virtually unreadable. There is no space to even indicate opening leads, and there should be a notes section, so that all of the details, especially in the no-trump opening section, can be put there, with just the basics in the box.
EBU cards are pretty well arranged, with space for relevant agreements and not, like the ACBL card, which uses valuable real estate for things that you don’t play don’t check the box for, plus is one side of less than A4, with basically no room for notes. EBU cards are also a bit easier to navigate then WBF cards. If some blanks were provided for the many Ebu players who are now playing online, it would be much appreciated

- Currently, different RAs require different system-card layouts.
- Foreigners and strangers tend to play systems unfamiliar to local players.
- Also local systems and local card-formats are often unfamiliar to foreigners and strangers.
- Hence basic system-cards should have the same clear simple standard format. everywhere.
- For high-level play, standard format supplementary-sheets should be mandatory.
- The WBF should get together with RAs like the ACBL, EBU (and BBO) to simplify and clarify a universal card.

I think you are underestimating the value of familiarity.
Generally people in Scotland hate the EBU20B card as being vastly inferior to the EBU20A card. Information is very hard to find and you cannot see all the detail that you need most often on one page, like you could with the EBU20A. The card also seems to waste a lot of space in case you may occasionally open one no trump with a singleton.
Bizarrely players in Scotland are far happier playing against a WBF system card, because it is used far more often here.
But I know EBU players tend to dislike the WBF card, mainly on the grounds of familiarity and especially the carding sections, although those that play here seem to cope well enough.
The ACBL card is not great but it does allow a new partnership to put a system together, of some sorts, in a very short time. Perhaps reflecting a difference that the card is designed for and the fact that it is a large homogeneous community.
I'd be happy enough if everyone adopted the USBF system summary form, which is a form of pre-alert that tells me the key things I should be concerned with. I provide a completely full WBF system card with six pages of supplementary notes, but it is a bit intimidating and it seems that the directors prefer it rather than the opponents.

I do not know the difference between these.

Yes, well I would like the average English player to be accommodated. But even a WBF card would be vAptly superior to the ones provided by BBO. The latters usability could be improved, though, if people put new ideas on separate lines rather than jumble everything together.

You either have a different reality from ours or a different perception of it. Whereas in regular f2f club play about 70% of partnerships were more or less stable, online that has dropped well below 50% for us. Add in a few substitutes and that means 45% at most are playing with a regular partner and several are in pure guesswork mode.
Also the BBO "default" cards would be almost useless to our players - I guess the modern ACOL one might be useful in EBU.
